Electric A Current

Electric charge is carried by charged particles so an electric current is a flow of charged particles.

Electric a current.

A often shortened to amp is the base unit of electric current in the international system of units si. Using water pipe analogy we can visualize the electrical current as water current that flows in a pipe. If the two requirements of an electric circuit are met then charge will flow through the external circuit. The difference in electrical potential between two points measured in volts.

It is named after andré marie ampère 1775 1836 french mathematician and physicist considered the father of electrodynamics. The ampere ˈ æ m p ɪər æ m ˈ p ɪər or ˈ æ m p ɛər uk symbol. In alternating current the motion of the electric charges is periodically reversed. Electrical current is the flow rate of electric charge in electric field usually in electrical circuit.

The international system of units defines the ampere in terms of. An electric current is said to exist when there is a net flow of electric charge through a region. Using the word current in this context is to simply use it to say that something is happening in the wires charge is moving. An electric current is a flow of electric charge in a circuit.

An electric current is the rate of flow of electric charge past a point or region. Click again to see term 1 29. Electric current is defined as the rate at which charge flows through a surface the cross section of a wire for example. Despite referring to many different things the word current is often used by itself instead of the longer more formal electric current.

The adjective electric is implied by the context of the situation being described. In direct current it is not. It is said that there is a current a flow of charge. When two point of different electric potential are connected by a conductor charge flows so long as a potential difference exists.

More specifically the electric current is the rate of charge flow past a given point in an electric circuit. Electric current is electric charge in motion. The electrical current is measured in ampere amp unit.
